Why does diversity increase as height above land increases​
wolverine [178]

Biodiversity rises with altitude initially before falling with height beyond that. Up until it reaches a diversity peak at about 1 300 to 1 800 m.

  • The biodiversity increases at higher geographical locations because There are more hiding locations. They are better for crop growth. They frequently include more than one kind of habitat.
  • As latitude or altitude change, so does biodiversity. As we descend from high to low elevations, the diversity increases (i.e., from poles to equator).
  • While the environment is harsh and plants have a brief growing season in the temperate region, tropical rain forests provide year-round growth-friendly circumstances.
  • This enables the emergence and expansion of several species. On a mountain, there is an initial increase in species diversity after which there is a decline in species variety as you go up in elevation.
  • At higher elevations, temperature drops and seasonal variations increase, which significantly diminishes.
